Solana (SOL): An overview
Source: Solana.com
TheSolana blockchain stands out as a highly functional open-source project designed to propeldecentralized finance (DeFi) andnon-fungible token (NFT) marketplaces into the mainstream. Often compared toEthereum (ETH)and dubbed an "Ethereum killer," Solana's architecture is tailored for the rapid development and deployment of smart contracts anddecentralized applications (dApps).
A key aspect of Solana's scalability is its design philosophy of scaling natively withMoore's Law rather than relying on additional layers orsharding. This means that as computational capacity increases, so does the network's capacity, allowing it to handle more transactions and smart contracts.
Solana is engineered for mass adoption. Its architecture can theoretically support a potential maximum capacity of710,000 transactions per second (TPS) on a standard gigabit network and up to28.4 million TPS on a 40 gigabit network.
In practice, the network handles an average of3000to4000TPS with block times as short as400 milliseconds. This efficiency doesn't come at the cost of decentralization, as the network is secured by1,981 independent validator nodes, ensuring data security and resistance to censorship.
With over255 billion total transactions to date, Solana maintains transaction fees at an impressively low average of$0.00025. Additionally, the network demonstrates a commitment to environmental sustainability, boasting a net carbon impact of0%.
The platform's vibrant ecosystem is evidenced by over11.5 millionactive accounts and the minting of 21.9 millionNFTs. This thriving environment, combined with its technological prowess, positions Solana as a leading contender in the blockchain space.

SOL is not just a digital currency but a multifaceted asset central to the operation and security of the Solana blockchain. It plays multiple vital roles within its ecosystem:
- Micropayments:SOL enables micropayments, which are facilitated through fractional units called lamports. One lamport is equal to0.000000001 SOL. It is named in honor ofLeslie Lamport, a major technical influence on Solana.
- Transaction fees:SOL is used to pay for transaction fees on the Solana network.
- Rent mechanism: Solana employs arent system for data storage on the blockchain. Accounts are required to maintain a minimum balance of SOL to keep their data stored. If the balance falls below this minimum, the data may be temporarily removed but can be reinstated later. This approach ensures efficient utilization of storage space.
- Validator and delegator rewards:Validators and delegators are rewarded for their contributions to the network's security and operation. These rewards come from a portion of newlyminted SOL and transaction fees, depending on the amount of SOL staked, the set inflation rate, and the volume and complexity of transactions on the network.
- Access to Solana ecosystem: Holding SOL tokens grants users access to a wide range of projects built on the Solana network, including various dApps and financial services.
At its inception,500,000,000 SOL were created in thegenesis block. Interestingly, there isn't a set cap on SOL's maximum supply. The token's inflation dynamics started at an8% rate. This inflation rate is set to undergo a15% reduction each year, and over time, it will stabilize, settling at a consistent long-term inflation rate of1.5%.
Additionally, the protocol has been designed such that half of each transaction fee gets burned. Consequently, as the transaction volume surges, it will naturally slow the expansion of the circulating supply. As of December 2023, the total supply stands at565,215,781SOL, out of which427,843,398 are in circulation.
How does Solana work?

Solana's architecture is unique, employing a combination of several mechanisms. The groundbreaking innovations that fuel the network are as follows:
Proof-of-History (PoH)
PoH is a novel concept in blockchain technology, acting as adecentralized clock for the Solana network. It creates a historical record that proves that an event, like a transaction, occurred at a specific time.
PoH works by taking the output of a previous operation and using it as the input for the next, creating a long, unbreakable chain of events. This allows the network to establish the order of events and the passage of time between them, significantly reducing the time needed for consensus. Solana’s network combinesPoS withPoH, creating a unique hybrid consensus mechanism.
Tower BFT
Tower BFT is Solana's customized version of thePractical Byzantine Fault Tolerance (PBFT)algorithm, optimized to work alongside PoH. It's a consensus mechanism that leverages the synchronized clock provided by PoH to reduce messagingoverhead andlatency. This means the network can reach consensus quickly and efficiently without sacrificing security.
Turbine
Turbine is a block propagation protocol. In simple terms, it breaks data into smaller packets, making it easier to send and receive blocks, even in a network with thousands of nodes. This protocol ensures that the network can handle large bandwidth demands, facilitating quick and efficient block propagation.
Gulf stream
Gulf Stream is Solana'smempool-less transaction forwarding protocol. It allows validators to execute transactions ahead of time, reducing confirmation time and memory load on validators.
Sealevel
On many blockchains,smart contracts are processed one at a time. Sealevel, however, allows for parallel processing of smart contracts, ensuring multiple contracts can run simultaneously without bottlenecking the system. This parallelism makes Solana one of the fastest blockchains.
Pipeline
The Pipeline is a transaction processing unit forvalidation optimization. It's essentially a set of processing units organized to validate transactions efficiently. This mechanism allows the network to quickly validate transactions and smart contract executions by streamlining them through different stages of the process.
Cloudbreak
Cloudbreak is a horizontally scaled accounts database. It's designed to organize the database in such a way that it can handle concurrent reads and writes across the network, ensuring that as the database grows, its performance doesn't degrade.
Solana programs
Solana programs, also known as smart contracts on other blockchain platforms, are the executable codes that process instructions in each transaction on the blockchain. They can be integrated into the network's core asnative programs or can be created and published by anyone ason-chain programs.
These programs form the fundamental components of the network, managing various functions such as transferring tokens between wallets, processing votes in DAOs, and keeping track of NFT ownership.
Archivers
In the Solana network, archivers are nodes used fordistributed ledger storage. They offload the burden of data storage from validators, enabling the network to store more data without compromising on speed or efficiency.
Solana cluster
A Solana cluster consists of a network of independently operated computers that collaborate (and occasionally compete) to validate the results of untrusted, user-submitted programs. This cluster is utilized whenever a user needs to maintain a permanent record of events over time or for theprogrammatic interpretation of those events.
Solana Program Library-20 (SPL-20)
SPL-20 is a pivotal token standard within the Solana blockchain framework. It outlines a comprehensive set of protocols and guidelines for the creation and management of digitaltokens on the Solana network.
Drawing inspiration fromBitcoin's BRC-20 standard, SPL-20 allows for the direct on-chain storage of digital artwork and various other digital assets.
The inception of Solana

In late 2017, Anatoly Yakovenko introduced the foundational concept for Solana by releasing a draftwhite paper. This whitepaper detailed a unique timekeeping method for distributed systems, termed PoH.
Yakovenko teamed up with Greg Fitzgerald, a former colleague from Qualcomm. Their collaboration led to the creation of a PoH blockchain testnet.
The project was initially calledLoom but was rebranded to Solana in 2018 to avoid confusion with another project. By February 2018, they had released the project's official paper alongside the internal testnet. 2018 also marked the formation ofSolana Labs, which began its fundraising activities during the same year.
The team successfully raised over$20 million in a private Series A funding round that extended into 2019. Solana'smainnet was officially launched in March 2020.
Subsequent to this launch, Solana secured an additional$1.76 million through a public token sale. This sale was facilitated by the cryptocurrency auction platform—CoinList.
WhileSolana Labsremains the primary contributor to the network, there is also theSolana Foundation. This non-profit organization, based in Zug, Switzerland, provides financial support for ongoing development. Moreover, it plays a pivotal role in fostering community-building activities for the blockchain.
